 Hi dear 
I follow your steps but the  matlab gave me this message

Warning: The model 'untitled' does not have continuous states, hence Simulink is using the solver 'VariableStepDiscrete' instead of solver 'ode45'. You can disable this diagnostic by explicitly specifying a discrete solver in the solver tab of the Configuration Parameters dialog, or by setting the 'Automatic solver parameter selection' diagnostic to 'none' in the Diagnostics tab of the Configuration Parameters dialog Warning: The model 'untitled' does not have continuous states, hence Simulink is using the solver 'VariableStepDiscrete' instead of solver 'ode45'.

Find the Configuration Parameters dialog and make the suggested adjustments. (It may continue to make suggestions until it is happy with your settings.)

Simulation->Model Configuration Parameters->Solver->Solver: Discrete

this is the matlab code i want to plot it in scope

please help me to solve this problem

fs=20E9;%sample rate-10 times the highest frequency

ts=1/fs;%sample period

t=[(-4E-9-ts):ts:(4E-9-ts)];%vector with sample instants

t1=.5E-9;%pulse width(0.5 nanoseconds)

x=(t/t1).*(t/t1);%x=(t^2/t1^2)(square of (t/t1)

A=1;%positive value gives negative going monopulse;neg value gives %positive going monopulse

y=A*(t/t1).*exp(-x);%first derivative of Gaussian pulse function

plot(t,y)

So use

[t',y']

in your "from workspace" block.

And change the simulation run time (next to the play block) to be your tmax (3.9500e-09).

You also have a to solve the problem where you have negative time. Since simulink doesn't do negative time. Perhaps add an offset?
